I&#39;d like to ask how to modify the number of subscribe address number? Is changing DSM_NONVIRTUAL_ADDR_MAXen-USTelligent Community 13Mon, 08 Jul 2019 13:07:11 GMThttps://devzone.nordicsemi.com/thread/197149?ContentTypeID=1Mon, 08 Jul 2019 13:07:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75bc57e2-ee44-4acb-91d6-391bb589f926tesc<p>Hi,</p> <p>In order to increase the number of addresses to subscribe to, you should not need to increase ACCESS_SUBSCRIPTION_LIST_COUNT. That value is for describing how many models would need to store a subscription list. If you do not increase the number of models, you do not need to increase this value either. (See also the documentation comment for ACCESS_SUBSCRIPTION_LIST_COUNT in nrf_mesh_config_app.h, which you find for instance under examples/light_switch/client/include/)</p> <p>You will typically get that assert if you do increase ACCESS_SUBSCRIPTION_LIST_COUNT, but you did not increase ACCESS_MODEL_COUNT. In your case it seems neither of them should be increased.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
